| Last year a friend of mine and I put together a PSL from a Romanian parts kit and receiver. It's all good to go except for that the scope rail won't fit the side mount correctly. The rail is much too thick. I had to do a lot of grinding on the receiver to get the gun functional and now this appears to need even more and the steel is harder than anything I've ever worked with before. Is there a preferred way to go about getting this done properly or anyone I can pay to get it fitted? I've been working at it bit by bit with a triangular file but it's taking forever and I'm worried about not getting it uniform across the whole length of it. Any pointers on this? |

Sounds familiar. I just ran into this and used my Bridgeport milling machine with a 60 degree dovetail cutter to accomplish the job. The steel used on the rail isn't hard at all. It cuts pretty easy but that's on a miling machine. The mount itself is a pot metal aluminum....very soft. In fact I didn't cut the rail at all ofhter than using a mill for milling/squaring the pocket where the stop pin on the scope mount itself contacts. Most of the work I did was on the mount.
My skills were called upon to get a LPS scope to fit on a Romanian FPK Dragunov type for my bosses husband. The rail on the rifle was not machined properly or completely as far as the width of the dovetail and the stopping area where the pin rests on the front of the rail. I had to machine the area in the front part of the rail to provide a good 90 degree stop for the pin. After machining that area I refinished it in the flat moly resin. I had to remachine and open the dovetail on the LPS mount about .035" wider. It had to be just enough to slide on and not wobble. I removed the damaged stop pin, threaded the hole and put a long set screw with turned end for the stop contact point. After that was completed I refinished it in moly resin too. Then I applied locktite to the long set screw/stop pin to keep it from backing out in either direction. Then I remachined and stoned the locking clamp to provide a good surface for the clamp to apply consistent pressure on the rail. After assembling I put it on rifle for complete satisfaction. It fits like a glove! Heres some pics...... Mount before machine and refinish
